Anime · .ass · keeps styling
To translate anime subtitles, upload your .ass, .ssa, or .srt file, choose a target language, and download — SubLingo rewrites only the dialogue and keeps every style, karaoke effect, position, and timecode exactly as the fansub made them. Unlike a browser extension that overlays subtitles on a streaming tab, this gives you a portable file that plays offline in mpv, VLC, or Plex on your own episodes. Source language is auto-detected, so Japanese needs no setup; translate into English or any of 100+ languages, with optional Japanese + English bilingual output for immersion learning. Free, no signup, no file-size cap.

Supports .srt, .vtt, and .ass / .ssa
Drop in your anime .ass, .ssa, or .srt file. SubLingo parses the dialogue and locks every timecode and style tag.
Set the target language (English by default). Source language is auto-detected, so Japanese needs no setup.
Only the dialogue text is rewritten. Styling, karaoke, positioning, and timing are preserved exactly.
Download the translated file and load it in mpv, VLC, or Plex — offline, no extension required.
Anime subtitles usually ship as Advanced SubStation Alpha (.ass) because the format carries fonts, colours, sign typesetting, and karaoke timing that plain .srt cannot. Overlay extensions ignore all of that — they render their own text on top of a streaming player. SubLingo keeps the original .ass intact and translates only the dialogue, so a translated file looks like the fansub did. That matters for downloaded episodes you watch in mpv or Plex, and for the local files immersion learners collect from archives like Kitsunekko. If you only need plain text, you can also convert .ass to .srt first.
Turn on bilingual output to keep the Japanese line and the English translation together under one timecode. It is one of the most effective comprehensible-input setups: you read the Japanese, glance at the English only when needed, and never pause to switch tracks. Make a dual-language file once and reuse it every rewatch.
Upload the .ass or .ssa file, set the target language to English (the source is auto-detected, so Japanese works without picking it), and download the translated file. SubLingo rewrites only the dialogue text, so every timecode, style, and effect stays intact and the file drops straight back into your player.
Yes. Advanced SubStation Alpha (.ass/.ssa) files carry styles, fonts, colours, positioning, and karaoke timing through override tags. SubLingo translates only the visible dialogue text and leaves every tag and the [V4+ Styles] and [Script Info] sections untouched, so signs, songs, and typesetting render exactly as the fansub intended.
Yes. The .ass and .srt files from subtitle archives like Kitsunekko work directly — upload one, choose your language, and download. This is built for immersion learners and viewers who keep local subtitle files for mpv or Plex, rather than watching through a browser extension on a streaming site.
Extensions overlay translated subtitles only while a supported site plays in a browser tab. SubLingo translates the subtitle file itself, so the result is a portable .ass or .srt you can keep and play offline in mpv, VLC, or Plex on any device — on your own episodes and downloads, not just on streaming sites the extension supports.
Yes. Turn on Bilingual to stack the original Japanese line and the English translation under one timecode in a single file. Learners put the language they are studying on top and the translation below, then watch in mpv or Plex without pausing to switch tracks. The timing stays frame-accurate.
Yes. The output is an ordinary subtitle file, so every offline player reads it. Name it to match the video file (episode.mkv → episode.ass) and drop it in the same folder, or load it from the player's subtitle menu. No extension, no plugin, no account.
Yes — free, with no signup and no file-size cap, so a full anime episode or a whole season's files translate without limits. Everything runs in your browser; upload, translate, and download.
